In the Archbishop's case it was deemed necessary, in order to fulfil the requirements of Canon Law, that he should be tried by the Pope himself. He was accordingly informed that his sovereigns had "denounced" him to the Pope, and that His Holiness had commissioned the Cardinal Du Puy, Prefect of the Inquisition, to act on his behalf, and that Du Puy had delegated the duty to James Brooks, who had succeeded Hooper as Bishop of Gloucester, to the Dean of St. Paul's, and to the Archdeacon of Canterbury. The trial took place in St. Mary's Church. The accusers, Philip and Mary, were represented by Drs. Martyn and Story. They, in the name of their sovereigns, presented a lengthy indictment, in which the chief charges were adultery, perjury, and heresy. The first meant that although a priest he had been married, and had even married a second time after he had been made an Archbishop; the second, that he had sworn obedience to the Pope and broken his oath; and the third, that he had denied the doctrine of transubstantiation.[510] Cranmer refused to acknowledge the jurisdiction of his judges, but answered the charges brought against him to his accusers because they represented his sovereigns. He denied that the Pope had any ecclesiastical power within England; but submitted to the kingly supremacy. As Brooks had no authority from the Pope to do more than hear the case, no judgment was pronounced; it was only intimated that the proceedings would be reported to Rome. Cranmer was conducted back to his prison. There he addressed first one, then a second letter to the Queen.[511] In dignified and perfectly respectful language he expressed the degradation of the kingdom exhibited in the act of the sovereigns appealing to an "outward judge, or to an authority coming from any person out of this realm" to judge between them and one of their own subjects. Cranmer early in his career had come to the unalterable opinion that the papal supremacy was responsible for the abuses and disorders in the mediæval Church, and that reformation was impossible so long as it was maintained. In common with every thoughtful man of his generation, he repudiated the whole structure of papal claims built up by the Roman Curia during the fifteenth century, and held that it was in every way incompatible with the loyalty which every subject owed to his sovereign and to the laws of his country. He took his stand on this conviction. "Ignorance, I know," he said, "may excuse other men; but he that knoweth how prejudicial and injurious the power and authority which the Pope challengeth everywhere is to the Crown, laws, and customs of this realm, and yet will allow the same, I cannot see in anywise how he can keep his due allegiance, fidelity, and truth to the Crown and slate of this realm."
